Anton Khirnov 25c98566e8 fftools/ffmpeg_opt: drop HAS_ARG from auto{scale,rotate} 
It causes those options to be parsed as either
* -autofoo 0/1 (with an argument)
* -noautofoo   (without an argument)
This is unnecessary, confusing, and against the documentation; these are
also the only two bool options that take an argument.

This should not affect the users, as these options are on by default,
and are supposed to be used as -nofoo per the documentation.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
